| 2 | Advanced optimization of gas turbine aero-engine transient performance using linkage-learning genetic algorithm:PartⅡ,optimization in flight mission and controller gains correlation development显示文摘PartⅠhas illustrated the procedures to apply the Linkage Learning Genetic Algorithm(LLGA)in Gas Turbine Engine(GTE)controller gains tuning and generated the optimization results for runway conditions from idle to takeoff.However,the total pressure and temperature of the engine inlet vary as the changing of altitude and Mach number,which would lead to the variation in fuel flow supply regulation.As a result,the optimized gains in runway might not be suitable for other flight conditions.In order to maintain the optimal control performance,the GTE controller gains should be adjusted according to the flight conditions.This paper extends the application of the LLGA method to other flight conditions and then simulates a complete flight mission with different gains and weather condition configurations.For this purpose,the control parameters in the Simulink model of the GTE controller are first corrected by the weather condition in altitude.Then,a typical flight mission is defined and divided into different flight segments based on the altitude and Mach number configuration.One representative point is selected from each segment as the datum point for optimization process.After this step,the LLGA method is used to find the best gains combinations for different flight conditions and the differences in optimization effects for different flight conditions are analyzed subsequently.The simulation results show that the optimization effect of the control performance of each flight condition is dependent on the value of(θδ)~(1/2)and the optimal K_(pla)in some flight conditions is approximately equal to p hd times of the Kplavalue in sea level standard condition.Finally,the complete flight mission is simulated with different gains and weather condition configurations.The simulation results show that the engine performance has been greatly improved after optimization by LLGA in the transient state and the high altitude conditions.In other steady states,the optimization effect is not very obvious. | Yinfeng LIU Soheil JAFARI Theoklis NIKOLAIDIS | 2021 | Chinese Journal of Aeronautics2021,34,4: | 3 |
| 3 | Advanced optimization of gas turbine aero-engine transient performance using linkage-learning genetic algorithm:PartⅠ,building blocks detection and optimization in runway显示文摘This paper proposes a Linkage Learning Genetic Algorithm(LLGA)based on the messy Genetic Algorithm(mGA)to optimize the Min-Max fuel controller performance in Gas Turbine Engine(GTE).For this purpose,a GTE fuel controller Simulink model based on the Min-Max selection strategy is firstly built.Then,the objective function that considers both performance indices(response time and fuel consumption)and penalty items(fluctuation,tracking error,overspeed and acceleration/deceleration)is established to quantify the controller performance.Next,the task to optimize the fuel controller is converted to find the optimization gains combination that could minimize the objective function while satisfying constraints and limitations.In order to reduce the optimization time and to avoid trapping in the local optimums,two kinds of building block detection methods including lower fitness value method and bigger fitness value change method are proposed to determine the most important bits which have more contribution on fitness value of the chromosomes.Then the procedures to apply LLGA in controller gains tuning are specified stepwise and the optimization results in runway condition are depicted subsequently.Finally,the comparison is made between the LLGA and the simple GA in GTE controller optimization to confirm the effectiveness of the proposed approach.The results show that the LLGA method can get better solution than simple GA within the same iterations or optimization time.The extension applications of the LLGA method in other flight conditions and the complete flight mission simulation will be carried out in partⅡ. | Yinfeng LIU Soheil JAFARI Theoklis NIKOLAIDIS | 2021 | Chinese Journal of Aeronautics2021,34,4: | 2 |
| 4 | Biomass-based aligned carbon networks with double-layer construction for tunable electromagnetic shielding with ultra-low reflectivity显示文摘Nowadays,carbon frameworks derived from natural biomaterials have attracted extensive attention for electromagnetic interference(EMI)shielding due to their renewability and affordability.However,it is critical and challenging to achieve effective regulation of shielding effectiveness(SE)as well as weaken the strong EM reflection of highly conductive biomass-based carbon materials.Herein,commercial cotton pads with oriented structure were selected as carbonaceous precursor to fabricate aligned carbon networks by pyrolysis,and the EMI SE of the samples with increased temperature of 800-1000℃ can be accurately controlled in the effective range of~21.7-29.1,~27.7-37.1 and~32.7-43.3 d B with high reflection coefficient of>0.8 by changing the cross-angle between the electric-field direction of incident EM waves and the fiber-orientation direction due to the occurrence of opposite internal electric field.Moreover,the further construction of Salisbury absorber-liked double-layer structure could result in an ultralow reflection coefficient of only~0.06 but enhanced SE variation range up to~38.7-49.3 d B during the adjustment of cross-angle,possibly due to the destructive interference of EM waves in the double-layer carbon networks.This work would provide a simple and effective way for constructing high-performance biomass carbon materials with adjustable EMI shielding and ultra-low reflectivity. | Jiali Chen Da Yi Xichen Jia Guoqing Wang Zhouping Sun Lihua Zhang Yinfeng Liu Bin Shen Wenge Zheng | 2022 | Journal of Materials Science & Technology2022,,8: | 2 |

| 14 | Adding power of artificial intelligence to situational awareness of large interconnections dominated by inverter‐based resources显示文摘Large‐scale power systems exhibit more complex dynamics due to the increasing inte-gration of inverter‐based resources(IBRs).Therefore,there is an urgent need to enhance the situational awareness capability for better monitoring and control of power grids dominated by IBRs.As a pioneering Wide‐Area Measurement System,FNET/GridEye has developed and implemented various advanced applications based on the collected synchrophasor measurements to enhance the situational awareness capability of large‐scale power grids.This study provides an overview of the latest progress of FNET/GridEye.The sensors,communication,and data servers are upgraded to handle ultra‐high density synchrophasor and point‐on‐wave data to monitor system dynamics with more details.More importantly,several artificial intelligence(AI)‐based advanced appli-cations are introduced,including AI‐based inertia estimation,AI‐based disturbance size and location estimation,AI‐based system stability assessment,and AI‐based data authentication. | Lin Zhu Yinfeng Zhao Yi Cui Shutang You Wenpeng Yu Shengyuan Liu He Yin Chang Chen Yuru Wu Wei Qiu Mirka Mandich Hongyu Li Adedasola Ademola Chengwen Zhang Chujie Zeng Xinlan Jia Weikang Wang Haoyu Yuan Huaiguang Jiang Jin Tan Yilu Liu | 2021 | High Voltage2021,6,6: | 0 |
| 15 | IncPregeh an incremental graph parallel computation model显示文摘Large-scale graph computation is often required in a variety of emerging applications such as social network computation and Web services.Such graphs are typically large and frequently updated with minor changes.However, re-computing an entire graph when a few vertices or edges are updated is often prohibitively expensive.To reduce the cost of such updates,this study proposes an incremental graph com- putation model called IncPregel,which leverages the nonafter-effect property of the first-order Markov chain and provides incremental programming abstractions to avoid redundant computation and message communication.This is accomplished by employing an efficient and fine-grained reuse mechanism.We implemented this model on Hama,a popular open source framework based on Pregel,to construct an incremental graph processing system called IncHama.IncHama automatically detects changes in input in order to recognize 'changed vertices'and to exchange reusable data by means of shuffling.The evaluation results on large-scale graphs show that,compared with Hama,IncHama is 1.1- 2.7times faster and can reduce communication messages by more than 50%when the incremental edges increase in number from 0.1to 100k. | Qiang LIU Xiaoshe DONG Heng CHEN Yinfeng WANG | 2018 | Frontiers of Computer Science2018,12,6: | 0 |
| 16 | Security in Edge Blockchains:Attacks and Countermeasures显示文摘Edge blockchains,the blockchains running on edge computing infrastructures,have attracted a lot of attention in recent years.Thanks to data privacy,scalable computing resources,and distributed topology nature of edge computing,edge blockchains are considered promising solutions to facilitating future blockchain applications.However,edge blockchains face unique security issues caused by the de⁃ployment of vulnerable edge devices and networks,including supply chain attacks and insecure consensus offloading,which are mostly not well studied in previous literature.This paper is the first survey that discusses the attacks and countermeasures of edge blockchains.We first summarize the three-layer architecture of edge blockchains:blockchain management,blockchain consensus,and blockchain lightweight cli⁃ent.We then describe seven specific attacks on edge blockchain components and discuss the countermeasures.At last,we provide future re⁃search directions on securing edge blockchains.This survey will act as a guideline for researchers and developers to design and implement se⁃cure edge blockchains. | CAO Yinfeng CAO Jiannong WANG Yuqin WANG Kaile LIU Xun | 2022 | ZTE Communications2022,20,4: | 0 |

| 19 | Stem cell properties and neural differentiation of sheep amniotic epithelial cells显示文摘This study was designed to verify the stem cell properties of sheep amniotic epithelial cells and their capacity for neural differentiation. Immunofluorescence microscopy and reverse transcription-PCR revealed that the sheep amniotic epithelial cells were positive for the embryonic stem cell marker proteins SSEA-1, SSEA-3, SSEA-4, TRA-1-60 and TRA-1-81, and the totipotency-associated genes Oct-4, Sox-2 and Rex-1, but negative for Nanog. Amniotic epithelial cells expressed β-III-tubulin, glial fibrillary acidic protein, nestin and microtubule-associated protein-2 at 28 days after induction with serum-free neurobasal-A medium containing B-27. Thus, sheep amniotic epithelial cells could differentiate into neurons expressing β-III-tubulin and microtubule-associated protein-2, and glial-like cells expressing glial fibrillary acidic protein, under specific conditions. | Xuemin Zhu Xiumei Wang Guifang Cao Fengjun Liu Yinfeng Yang Xiaonan Li Yuling Zhang Yan Mi Junping Liu Lingli Zhang | 2013 | Neural Regeneration Research2013,8,13: | 0 |
| 20 | Implementing hardware primitives based on memristive spatiotemporal variability into cryptography applications显示文摘Implementing hardware primitives into cryptosystem has become a new trend in electronic community.Memristor,with intrinsic stochastic characteristics including the switching voltages,times and energies,as well as the fluctuations of the resistance state over time,could be a naturally good entropy source for cryptographic key generation.In this study,based on kinetic Monte Carlo Simula-tion,multiple Artificial Intelligence techniques,as well as kernel density map and time constant analysis,memristive spatiotemporal variability within graphene based conductive bridging RAM(CBRAM)have been synergistically analyzed to verify the inher-ent randomness of the memristive stochasticity.Moreover,the ran-dom number based on hardware primitives passed the Hamming Distance calculation with high randomness and uniqueness,and has been integrated into a Rivest-Shamir-Adleman(RSA)cryptosystem.The security of the holistic cryptosystem relies both the modular arithmetic algorithm and the intrinsic randomness of the hardware primitive(to be more reliable,the random num-ber could be as large as possible,better larger than 2048 bits as NIST suggested).The spatiotemporal-variability-based random number is highly random,physically unpredictable and machinelearningattack resilient,improving the robustness of the entire cryptosystem. | Bo Liu Yudi Zhao YinFeng Chang Han Hsiang Tai Hanyuan Liang Tsung-Cheng Chen Shiwei Feng Tuo-Hung Hou Chao-Sung Lai | 2023 | Chip2023,2,1: | 0 |
